A class’ constructor usually defines
a) how an object is initialized
b) how an object is interfaced
c) the number of instance data in the class
d) the number of methods in the class
e) if the instance data are accessible outside of the object directly
Answer: a. Explanation: The constructor should be used to “construct” the object, that is, to set up the initial values of the instance data. This is not essential, but is typically done. The interface of an object is dictated by the visibility modifiers used on the instance data and methods.
